Features and benefits

InstallationMounting on site

The compact size of the CGCLsimplifies the installation on site andits low wide profile allows it to passeasily through a door. The total areataken up by the unit is relativelysmall due to the reduced size.Anti-vibration pads are supplied asstandard to avoid direct contactbetween the unit base and themounting surface.

Water connections

The water connections are broughtto the outside of the unit so that it isnot necessary to remove or piercethe panels.

Electrical connections

Electrical cable gland located on theback of the panel allow for easyconnection of the power cable.A flow detection system is mountedas standard in the factory. It istherefore not necessary to fit a FlowSwitch on site.A dry contact is available on thecontrol module to control the waterpump contactor. Space is availablein the control panel to install thechilled water pump contactor(s).Water pump contactor can beinstalled by Trane as an option.

Reliable and quiet operationReliability

The use of the Scroll compressorsensures excellent reliability. Versus areciprocating compressor, the Scrollhas the following advantages.- 64 % fewer parts.- The Scroll compressor generatessignificantly less vibration thereforereducing the risk of discharge linefailure.

Performance

The absence of dead volume at theend of the compression cycleensures better performance.The absence of fragile moving parts,such as springs and valves, alsomeans that this performance ismaintained with time.

Part load performance

The Scroll compressor alwaysoperates at full load.The chiller capacity is a function ofthe number of compressors running.In this way the power factor ismaintained at a high level even atlow loads.

Low sound level

The Scroll compressor issignificantly less noisy andgenerates less vibration than areciprocating compressor.In addition, on sites where the noiselevel is critical, the compressors canbe fitted with an optional soundattenuating enclosure.

Reduced maintenance

The Scroll compressor does notrequire routine maintenance due tothe absence of fragile parts, such assprings and valves which requireregular replacement.

Other standard features• Thermal insulation of the water

connections, and of theevaporator.

• Loss of water flow protectionprovided by a differentialpressostat.

• Operation up to + 40°C externaltemperature.

• Shipped with rubber pads.• Centrifugal fans which allow to

obtain a static pressure up to500 Pa.

• A resistance heater placed on theevaporator to avoid freeze-up risk.The heater is energized only if theexternal temperature isbelow + 2°C.

• Pressure transducers to obtain anoptimal control of the fans and toallow to display the low and highrefrigerant pressure.

• Modem connection.• Electrical panel IP 55.

Control module SMM

(Scroll Manager Module)

Leaving chilled water

temperature controlThe chilled water temperature ismeasured at the evaporator outlet.The SMM module compares thisvalue with the setpoint and starts orstops the compressors following aPID algorithm.

Condensing pressure control

The SMM module controls the fanspeed operating in a way whichalways optimizes the COP and avoidHP or LP cut out.

Control

The SMM module includes thefollowing functions:• Short cycle protection taking into

account the frequency ofcompressor starts.

• Automatic restart after a powerfailure.

• Equalization of the number ofstarts and the operating hours ofthe compressors.

• Control of the chilled water pump.• Control of the evaporator anti-frost

heater.• Control of all safety and

protection.

Optimization

In order to reduce electricityconsumption the SMM module canautomatically adjust the chilledwater temperature setpoint inrelation to the outdoor temperature.

Communication

The SMM module can interface withdifferent types communicationsystems. These systems simplifyconsiderably the maintenance andcan supply information on theoperating conditions of the chiller.

Operator interface

The SMM module includes acommunication interface with aliquid crystal display. This interfaceprovides an accurate assessment ofthe chiller operating conditions andfacilitates a rapid diagnosis if asafety function is activated.

Remote control

The dry contacts and the analoginputs, provided as standard, allowfor the remote control andsurveillance of the chiller.If a safety function is activated anoutput via a dry contact is provided.Inputs are available to partially orcompletely stop the operation of thechiller. An analog input (4/20 mA or0/10 V) allows for the adjustment ofthe chilled water temperaturesetpoint.

Remote control via serial link

It is possible to integrate the CGCLunit into a BMS via a serial link withan optional TCI-S comunication card.The TCI-S allows to obtain a seriallink type RS232 or RS485 with aModbus protocol.

Notes

The manufacturer has a policy of continuousproduct improvement, and reserves the rightto alter any details of the products at any timewithout notice.

This publication is a general guide to install,use and properly maintain our products. Theinformation given may be different from thespecification for a particular country or for aspecific order. In this event, please refer toyour nearest office.

Safety recommendationsTo avoid accidents and damage, thefollowing recommendations shouldbe observed during maintenanceand service visits:1. The maximum allowable

pressures for system leak testingon low and high pressure side aregiven in the chapter “Installation”.Always provide a pressureregulator.

2. Disconnect the main supplybefore any servicing on the unit.

3. Service work on the refrigerationsystem and the electrical systemshould be carried out only byqualified and experiencedpersonnel.

Maintenance contractIt is strongly recommended that yousign a maintenance contract withyour local Service Agency. Thiscontract provides regularmaintenance of your installation bya specialist in our equipment.Regular maintenance ensures thatany malfunction is detected andcorrected in good time andminimizes the possibility thatserious damage will occur. Finally,regular maintenance ensures themaximum operating life of yourequipment. We would remind youthat failure to respect theseinstallation and maintenanceinstructions may result in immediatecancellation of the warranty.

TrainingThe equipment described in thismanual is the result of many yearsof research and continuousdevelopment. To assist you inobtaining the best use of it andmaintaining it in perfect operatingcondition over a long period of time,the manufacturer has at yourdisposal a refrigeration and airconditioning service school. Theprincipal aim of this is to giveoperators and technicians a betterknowledge of the equipment theyare using, or that is under theircharge. Emphasis is particularlygiven to the importance of periodicchecks on the unit operatingparameters as well as on preventivemaintenance, which reduces the costof owning the unit by avoidingserious and costly breakdown.
